The biological and sociological implications of diversity, equity, and inclusion (DEI): life within microbiomes and...

From a biological point of view, Diversity, Equity, and Inclusion (DEI) are important at multiple levels, which include our genetics, microbiomes, diets, and all organ system interactions. Considering only DEI's sociological aspects is equivalent to the error of "throwing out the baby with the bath water." Variances in microbial diversity within our microbiomes might affect our health through systemic interactions affecting metabolites, maintaining immune homeostasis, and wound healing of cellular damage from an infection, physical stress, or psychological trauma. An imbalance of our immune cell subsets, both innate and adaptive, and the microbes in any of our microbiomes might lead to more cellular damage from excessive inflammation and oxidative stress and less immune regulation. The immune dysregulation may occur due to the loss of endometrial barriers enabling the spread of microbes, environmental pollutants, and allergens. Heat waves, sleep deprivation, and increased prevalence of pollutants such as polychlorinated biphenyls, which weaken endothelial barriers, may be responsible for the enhanced prevalence of physical and psychological stresses. Leakage of our useful gut microbiota into the periphery might initiate inflammatory responses, and an altered gut microbiome might affect the gut-brain axis that influences physical and mental health.
